[issue28425] Python3 ignores __init__.py that are links to /dev/null

[Douglas Greiman]

Douglas Greiman added the comment:

To be thorough, I looked at non __init__.py source files as well, with erratic results.  And who knows what would happen on other OS's.  So a blanket "must be a regular file" seems reasonable.

$ ls -l b.*
lrwxrwxrwx 1 dgreiman eng 9 Dec  9 16:05 b.py -> /dev/null

$ python2.7 -m b             # Success
$ python2.7 -c 'import b'    # Success
$ python2.7 b.py             # Success

$ python3.5 b.py             # Success
$ python3.5 -m b             # Failure
/opt/python3.5/bin/python3.5: No module named b
$ python3.5 -c 'import b'    # Failure
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: No module named 'b'
